How we cite our quotes: (Story.Chapter.Paragraph)
Quote #1
"So I decided to see for myself," [Twoflower] was saying. "Eight years' saving up, this has cost me. But worth every half-rhinu. I mean, here I am. In Ankh-Morpork. Famed in song and story, I mean. In the streets that have known the tread of Heric Whiteblade, Hrun the Barbarian, and Bravd the Hublander, and the Weasel… It's all just like I imagined, you know." (1.6.3)
How important is exploration to the novel? It's basically the entire reason the novel takes place. Without the urge to explore, Twoflower would never have gotten on the boat. If he didn't get on the boat, he wouldn't have meet Rincewind. If he hadn't met Rincewind, well, you get the idea.
Quote #2
In the long afternoon they toured the city of Turnwise of the river. Twoflower led the way, with the strange picture box slung on a strap around his neck. Rincewind trailed behind, whimpering at intervals and checking to see that his head was still there. (1.12.1)
Rincewind acts as Twoflower's tour guide to Ankh-Morpork. At the same time, he becomes our guide to exploring Ankh-Morpork. Funny how that works, isn't it?
Quote #3
Rincewind stared muzzily at the recumbent tourist. At two recumbent tourists. (1.27.15)
Welcome to the party, Rincewind. He has now joined Twoflower and the readers as tourist of the Disc, though he has absolutely no desire to explore anything beyond a comfy room lacking in particularly sharp objects.
